Derrick Thomas leaves Boise State football

LAS VEGAS -- Boise State confirmed that backup running back Derrick Thomas left the football program on Monday.

No immediate details were provided by the University, however, head coach Bryan Harsin will be available for comment at Mountain West Media Days on Tuesday.

Back in the spring, Thomas said that he was looking to put last year behind him. The 2013 season was no doubt a disappointment. The Butler Community College transfer rushed for just 95 yards on 32 carries and he was suspended for the season opener at Washington and the bowl game against Oregon State.

During his press conference on March 19, Harsin acknowledge that Thomas has looked impressive during practice. But when he got an opportunity in the Blue and Orange Spring Scrimmage, fellow backup running backs Jack Fields and Devan Demas out performance him and secured their spots ahead of him on the depth chart.

Matt Miller has &quot;made plays in practice.&quot; Harsin also adds that Derrick Thomas, Jay Ajayi and Jack Fields have impressed on offense.
